Gender of this cross breed?

[dunedin]

This is my 12 week old Wyandotte cross (possible fathers are leghorn, light Sussex and Wyandotte) the comb and wattles made me think female but the one tail feather being so long and pointy has me second guessing. I've had a close look for pointy saddle and hackle feathers but they are still rounded.
Any thoughts?

100% pullet. Is she definitely a crossbreed? She looks like a purebred silver laced Wyandotte to me.
